LIQUID-FEEDING DEVICE.

Application filed June. 15,

To all whom it may conaem;

Be it known that I, CLARENCE B. DES JARDINs, a citizen of the UnitedStates,,residing at Toledo, in the county of Lucas and State of Ohio,have invented certain new and useful Improvements injLiquid- FeedingDevices of which Ideclare-the following to be a full, clear,andexactdescription.

The present invention relates to a. liquid feeding device and, has foritsobjectto provide more particularly,v improved means .for feedingga'solenev or other liquid fuel from. a relatively: low level such as.the supply. tank at the rear endof an automobile, to a. plurality offeed tanks or receptacles ele-; vated with respect to said supply, tankand arranged to provide a continuous flow of fuel to the carbureter ofthe engine orothen liquid receiving vessel, in order; that: a con? stantlevel may bemaintained therein, said fuel being forced into thefeedtanks by any suitable means, but. preferably by suction produced in theintake manifold of the en.- gine which, in the preferredembodimentof theinvention, is connected witlrthe supply tank. through said feed tanks.

A further. object of the invention is to provide a plurality. of. vacuumcontrolled feed tanks, preferably. two,.which. are elevated with respectto a liquidsupply source 3 and connected with an aspirator. on suctionproducing apparatusand" provided with means. for' alternately. placingsaid! tanks in communicationwith the aspirator for the purpose ofaffordingia. continuous-- feed or supply of fuelto a lowlevelreceivingvessel= such as. the carbureter: of EtILlIk ternal combustion 1 engine.

A. still further object: of the inventiolnis to provide animprovedvalvearrangement for alternately opening andf closing the: airy:inlet and suction controlled; passageways; communicating with two vacuumfuel 1 feed' tanks to flIlClffIOIlI-WVIIICIL liquid. is alteiw-e natelyfed and discharged. I p

Further objects, and ob ects1-relat1ng.to economies of.v manufacture anddetails of construction, will definitely appear from the engine by'meansof the suction detailed description to-follow: p

Referring. to the drawings, 1 represents an internal combustion engine:provided I with a, suitable .carbureter '2," and an; intake manifold 3forming the aspirator or suction producing apparatus for. lifting, the.liquidz'fuel from the 'mainlo'w leveltank or liquid 1 supply source 4through thelconduit;

5 to [the receptacle 6 'divided" by the. partition 7 to form theindependent; vacuum feed tanks having the liquid receiving chambers 8and 9 from which the'liquid'is alternately T i fed by gravity to thecarburetorthrough'the conduit 10, said; tanks or chambers beingconnected with the intake manifold of the with the branch pipes 13 andll eonnected' preferably with the elbows 16 and 17 from, which extend theconnections 18 and 19 pro-i jecting through the cover 20 of the tanksinto the chambers 8 and 9, respectively, whichare securedoupon the coverby means of the inner and outer lockin nuts 21 and 22, as clearly shownin Fig. I

The suction conduit 11 is connected with the threaded portion 24 of thevalve casing 25 from which extends through the cover 20 and into theliquid receiving chambers 8 and 9, the threaded connections 26 and 27,respectively, each being provided with a suction passageway leading tothe valve chamber in which is mounted the valve 28 having the recess 29adapted to alternately establish communication between said chambers andsaid suction conduit, whereby the liquid is fed first into one of thefeed tanks and then into the other.

The valve casing and connections 26 and 27 are preferably integral andthe portions of the casing having the horizontal passageways arepreferably bored through from the ends of the valve chamber for the sakeof economy in manufacture and are then plugged b means of the screws 30,as shown in Fig. IL. The connections 26 and 27 are preferably secured inposition upon the cover 20 by means of inner and outer lock nuts 31which are threaded upon said connections on the opposite sides of thecover.

The air inlet passageways for alternately venting each of the feed tankswhen the other is in communication with the suction producing apparatusare formed through the valve casing 32 in which is mounted the valve 33provided with the oppositely positioned recesses 34 and 35, as shown inFig. IV.

The valve casing 32 is supported preferably by the elbows 36 and shortnipples or connections 37 and 38, the former extending into the feedchamber 8 and the latter into the feed chamber 9 and each beingpreferably threaded to receive the locking nuts 39 on the opposite sidesof the cover 20.

The air inlet passageway 40 leading to the chamber 8 is adapted to beclosed by the valve 33 when the valve 28 is in position to open thesuction passageway leading to said chamber, but at the same time, theair inlet passageway 41 leading to the chamber 9 is open. Thisoperation, of course, is reversed when the valve 28 is in position toopen the suction passageway leading to the chamber 9.

The air inlet passageways 40 and 41 are adapted to communicate with thevertically disposed passageway 42 through the recesses 34 and 35respectively of the valve 33 when the latter is moved to its extremepositions of travel in a manner which will presently be described.

The valves 28 and 33 preferably comprise the opposite ends of a cylinderwhich extend through the spaced valve casings 25 and 32 to receive thewashers 43 and nuts 44, as shown in Fig. V. I preferably make the valvecasings in separate parts rather than integral and the valves in onepiece in preference to separating them, but do not wish to limit thesame to this particular form of construction.

The valve or valves are actuated by the lever arm 45 extending betweenthe valve casings from the central or connecting portion of the valves,as shown in Figs. II and V.

The arm is actuated by the float 46 in the tank 8 when said floatreaches predetermined points in its up and down movement within thetank, as will hereinafter appear.

The float is provided with a centrally disposed sleeve 47 through whichextends the guide post 48, the upper end of which is reduced andprojected through an opening in the cover 20 and adapted to receive thenut 49, between the inner face of which and the outer end of the reducedportion of the post is provided the packing 50, the lower end of saidpost being preferably projected through the bottom wall of the tank, asshown in Fig. III.

The post at its upper end is provided with a longitudinally disposedbore 51 into which extends the valve lever actuating'rod 52, said rodbeing also projected through the nut 49 and packing 50 and provided witha hooked end 53 engaging the arm or lever 45 within the slot 54 at itsouter end, as shown in Figs. III and VI.

A transverse slot 55 in the post 48 intersects the bore 51 and registerswith the oppositely positioned slots 56 in the float sleeve 47. Extendedthrough said slots and the bottom of the rod 52 is a pin 57 which isfreely movable within the slots. The opposite ends of the pin, in thepreferred embodiment of the invention, project through the elongatedslots 58 formed in the enlarged ends 59 of the arms 60 which are pivotedat 61 upon the post 62 extending downwardly from the cover 20, as shownin Fig. III.

Connected with the outer ends of the pin 57 are the coil springs 63extending longitudinally of the arms 60, said springs being anchored tothe clips or brackets 64 upon the side wall of the tank, as shown inFig. III. v The sleeve 47 is provided with the upper and lowerprojections 65 and 65 respectively, which are preferably in the form ofannular rings and which, when the float 46 is moved up and down by therise and fall of liquid in the tank, engage the enlarged ends 59 of thearms 60 to move the latter upon their pivots, whereby when the springs63 are carried past said pivotal points, either in the up or downmovement of the float, the valve operating rod 52 will messes; f Y)beactuated by the tripping action of the tanks in communication with theintake manifold of the engine or whatever form of aspirator it isdesired to use.

The liquid is preferably discharged from the feed chamber 8 through thepassageway 66 in the bottom of the post 47, the latter.

being threaded exteriorly of the tank to receive the elbow 66' connectedwith the'conduit 10 leading to the carbureter by means of the short pipe67 and T-head 68, as'shown in Fig. III.

Liquid from the feed chamber 9 is dis charged into the conduit 10through the nipple 69, elbow 70, short pipe 71 and T-head 68, saidnipple being threaded to receive the nut 7 2 onthe inner face of thetank and the elbow o l-the outer face, as shown in Fig. III The elbows66' and 70 are each provided with a valve seat 7 3 and a ball valve 74for preventing the flow of liquid upwardly, into the tanks 8 and 9, thusavoiding the mere transfer of liquid from the tank which, is underatmospheric pressure to the tank which is under suction.

The elbows containing the ball valves are adapted to be drained byremoving the thumb screws 75 shown in III.

In order to prevent the possible withdrawal by suction of the liquidfrom the feed chamber 9 through the connection 27 of the valve casing25in cases where the chamber 9 might be filled faster than the chamber 8is emptied, I provide the valve 76 adaptedto be moved into engagementwith the seatv 77 on the lower end of said connection 27 by movement ofthe float 78 on the guide post 79. when the liquid in the chamber hasreached a predetermined height. By this means, the supply of fuel. tosaid cham her at each filling operation is. limited to a predeterminedamount, which is approximately the amount fed to the chamber 8 at thetime the suction passageway leading thereto is closed by the, valve 28.

I am aware that the particular embodiment of my invention, which I havehere, shown and described, is susceptible of considerablevariationwithout departing from the spirit thereof, and, therefore, Idesire to claim the same broadly, as well as specifically, as indicatedby the appended claims,
